simultaneously with the actuation of the pusher rod 2 The mechanicaltransmission for automatically performing the above-mentioned operationswill now be described. The main drive sleeve is continually rotatedduring the operation of themac'hine by any suitable or preferred sourceof power, such, for instance, as an electric motor 36su1tably mounted inan out of the way place on a bracket 37 on the side of the frame 10. Asprocket chain 38 engaging suitable sprockets drives the shaft 39 at areduced speed from the motor 36, which last-mentioned shaftthroughsuitable reduction gearing drives a sleeve 40 on a secondintermediate shaft 41.

40 to drive the intermediate shaft:41 on which it is splined. Lastly, apinion on the intermediate shaft 41 meshing with a gear 44 on the maindrive sleeve 35 transmits motion to said sleeve.

The sleeve 35 carries a single cam 45 adapted to actuate alternatelyeach of two rollers 46 and 47, one located above and the other below theaxis of rotation of the cam. WVhile separate cams for the rollers mightobviously be provided we prefer the construction shown. The lower roller47 is suitably supported on a shaft 48 extending through centrallyupstanding lugs on the lower cross head 20 and also through one of theselugs laterally to 2. lug 51 near the end of the cross head. ably pivotedon a transverseshaft 53 has a bifurcated end straddling the shaft '48and at its other end is adapted to actuate a vertical plunger 54 througha short connecting link 55 pivotally connectedto the plunger 54 and thelever 52. The plunger 54 reciprocates vertically in suitable guidebearings carried by the frame 10. A stationary knife blade 55 is locatedbelow the center of the table 12 above the path of the paper from thepaper roller 34. A movable cutting blade 56 suitably pivoted at 57receives motion from the vertical plunger 54 through a short connectinglink 58 pivoted to the plunger and cutting knife.

As the cam 45 rotates in a clockwise direc- A suitable. toothed clutch42 is adapted toengage the sleeve A lever 52 suittion from the positionshown in Fig. 2 the lower roller 47 will be forced down, moving thelower cross head, guide rods, upper cross head and cutting knife 14 downto bring the knife against the table 12. The movable cuttin blade 56will also be actuated throug the vertical plunger 54 and lever 52 tosever the paper extending from the roll onto the conveyor belt. We haveprovided means for holding the roller 47 against the cam 45 and returning it to its uppermost position after the projecting portion of the camhas passed by, in the shape of a suitable counterweight 59 mounted onthe end of a pivoted lever 60. The roller 61 on the opposite end of thelever bears against a suitable surface providedon the lower crosshead 20in all positions of the lever and crosshead.

After the main cutting knife 14 and paper rout-ting knife 56 have beenactuated as above described and returned to their initial positions, thecam 45 in its further rotation will actuate the upper roller 46 moving abell crank lever 62, resiliently urged toward the position illustratedinFig. 2, by a suitable tension spring 63 connected into the center of atension member 64 extending from the upwardly directed arm of the bellcrank lever to a suitable attachment on the frame 10. The motion of thebell crank lever 62 actuates suitable mechanism for feeding the pusherrod 29, the paper from the paper roll 34, and the conveyor belt 33. Theconnections for this purpose include a guide rod 65 sliding in suitableguide bearings 66 and 67 and carrying a head 68 connected through apivoted link 69. with the upper end of the upper arm of the bell cranklever 62. A turn-buckle 70 maybe provided as part of this link foradjusting the stroke of the head 68. At its rear end the guide rodcarries an inwardly projecting forwarding plate 71 extendmg across underthe pusher rod 29 and car-' rying the dog'31 pivotally mounted betweensuitable upstanding lugs or cars 72-.

The conveyor belt 33 is carried by rollers 73 and 74, the outer roller74 being mounted on a longitudinally slidable bearing, sliding in theslot 7 5 at the end of the projecting arms 75 and adjustably tensionedby means of suitable springs 76. A short endless chain 77 passing over asprocket wheel 78 on the shaft of the inner roller 73 and an idlersprocket 79 slidably mounted by means of the slotted connectionindicated. at 80 to properlytension the chain, has a plurality ofequally spaced special links formed in its upwardly projecting dogs 81.Upon each actuation of the crosshead 68, a ratchet 82 mounted thereon isadapted to engage the next in succession of the dogs 81 to rotate theroller -73 and actuate the conveyor belt.

. A paper feedroller 83 of the same size as the rollers for thereceiving belt 1s dr ven from the inner roller 73 at the same speed by asuitable sprocket chain 84. A smaller rubber faced roller 85 geared tothe paper feed roller so as to have the same surface 34 through suitableguides .86 past the cutting edge of the stationary knife 56 and forwardonto the conveyor belt. The stroke of the dog 31 and the ratchet 82 isdesigned to be appreciably greater than the distance between thesuccessive notches 30 or dogs 81 respectively, with which they engage,so that upon each. actuation of the bell crank lever 62 these part willmove up behind the next in succession of the parts they actuate andforce them forward to a certain point.

The frame 10 is U-shaped in end view and reinforced by stretcher rods103 which rods also act as pintles for the lower edges of doors 104,equipped with. suitable latches 105 and knobs 106. Except for slots 107to allow reciprocation. of the lower cross head 20, these doors and thewalls of the frame 10 constitute a complete enclosure for themovingparts under the table 12.

Suitable safety means are'provided to prevent actuation of the pusherrod 29 far enough to move. the pusher plate 26 under the cutting.lrnife. We havepv provided a hand control lever 87 mounted on a controlshaft 88 journaled in suitable bearings '89.

a l. crank arm 90 on theend of the shaft 88.

through a pivotally connected link 91, actuates the lever 92 to rotatethe clutch shaft 93 to engage the clutch 42- with thesleeve and starttheoperation of tlie machine. In doing this, the link 91 is swung intoalinement with the crank arm 90 and the long arm of the lever 92 rises,tensioning'the spring 94. It will be apparent that as soon as the handlever 87 is moved enough to throw the crank 90 and link 91 out ofalinement. the spring will immediately throw out the clutch. An upwardlyprojecting arm 95 carried by the shaft88 and in this instance formedintegral with the hand lever 87 is connected to a transversely slidableplunger 96'by a suitable link 97. Theplunger 96 as clearly indicated inFig. 1 carries a roller 98 at its outer end. A safety dog 99 mounted forlongitudinal adjustment on the pusher rod 29 and suitably clamped inposition by screws 100 is adapted to engage a roller on the end of a.slightly bent lever 101 carried by the forwarding plate '71. Thislever idownwardly offset as indicated in Fig. 2,

and its short arm underlies the forwarding plate 71 and is adapted toengage the roll-er on the plunger 96. A light tension spring 102 isadapted to hold the lever 101 in the position indicated in Fig. 1.

provided. An operator or Actuation-of the hand lever 87 to start themachine will move the plunger from the position illustrated in Fig. 1into rather close proximity to the short arm of the lever 101.

The step-by-step operation of the pusher rod 29 will eventually bringthe safety dog "99 where the return stroke of the forwarding plate willforce the end of the lever against the dog, rotating the lever so thatits short arm will engage the roller 98, displacing the hand leverslightly whereupon the spring 94 will act and release the clutch.

Itis desirable that the rod 29 should be released at the end of eachforward stroke of the plate 71 so that it may be slid back to itsinitial position; Thi facilitates handling masses of cream of varioussizes. e have provided a stationary bar 108 extending parallel to therod 29 and having an upwardly projecting cam portion 109. A small pin110 projects laterally from the dog 31 and in its rearmost positionrides up on the cam 109, lifting the dog 31 clear of the teeth'30.

The operation of the device is as follows: in cutting quarts the knife32 is not used and a detachable plate 111 (see Fig. 5) forms the frontedge of the table 12. The synchronous operation of the belt v33 andpusher plate 26 will operate to carry away the last brick, if any, andto project the end of the mass of cream, as indicated in dotted lines at112, past the edge of the table. The plunger arm and belt then come torest and the knife 14 severe the projecting mass of cream which fallsonto the piece of paper carried partly out from underthe edge of thetable by the last motion of the belt 33. Simultaneously with the cuttingof the cream another length-ofpaper on the belt 33 under the table issevered by the knife 56.

A wrapping table 113, underlying the belt- 33 and projecting laterallyon each side thereof, as illustrated in Fig. 5, is preferably operatorsmay stand on one or both sides of the belt 33 and by grasping the edgesof the pieces of paper on which the bricks are laid, draw them to oneside onto the lateral projections of the table where they may beconveniently wrapped in the paper. Ne may also provide a suitablecontinuously moving belt 114 adapted to receive objects falling off theend of belt 33 to convey them in any desired direction. lVhen the belt114 is used, the wrapped bricks are laid back on the belt '33 anddeposited by it on the belt 114 which may convey them to any desiredpoint for packing, storing or shipping pur- (see Fig. 1) and the knifemounted on the machine each half as Wide as i the paper used forwrapping quarts, and the laterally directed pint bricks will fall sideby side, each on a separate piece of paper.

Whilewe have illustrated and described in detail the particularembodiment of our invention at present preferred it should be clearlyunderstood that the description is only for the purpose of illustrationand many variations and modifications will naturally 0:.cur to thoseskilled in the art. It will, for instance, be obvious that increasingthe distance by which the table projects past the vertical plane of thecutting knife 1 L, may cause the severed brick to fall off the tableduring actuation of the pusher plate 26 and belt 33 instead of duringactuation of the knife to sever the brick as illustrated.
